Whoa. Check this out. That is a lava tube, which is an underground channel that used
-
to carry molten lava, but is now home to extremophiles. These tubes are super cool,
-
but I’m not here to look for life. I’m here to look for xenoliths, which are some of the
-
oldest rocks on earth. They can be billions of years old. By analyzing this type of rock
-
and trying to figure out what they’re made of, we can then correlate it with the supernova that was
-
potentially responsible for their formation. Now that’s a big deal, like trying to figure out how
-
the solar system was formed big deal. After 40 minutes of walking on Mars, we made it.
-
We got data. We’re seeing lots of heavy elements like silicon,
-
iron, magnesium and those are very common elements churned up in the core of stars.
-
Okay. I think I got what we need. Let's head back to the Hab. Let us know in the comments
-
if you want to learn more about my mission in a Mars simulation. Thanks for watching.
